About
Jun Ojima is a leading researcher in occupational health and industrial hygiene, with a primary focus on the hazards associated with arc welding. His work systematically addresses the critical risks welders face, including exposure to ultraviolet radiation (UVR), toxic fumes, and hazardous gases. Ojima’s major contributions include pioneering laboratory measurements of UVR emissions from CO₂ arc welding, which are essential for preventing acute injuries like photokeratoconjunctivitis. He also conducted detailed assessments of fume and gas concentrations at the welder’s breathing zone, providing foundational data on exposure to ozone, carbon monoxide, and heavy metals such as manganese and chromium. Notably, his research on ventilation efficiency in confined spaces, combining experimental simulations with numerical modeling, has directly informed safer welding practices and workplace design. With over 80 citations across his most influential papers, Ojima’s work has had a lasting impact on industrial safety standards. His development of an animal inhalation exposure chamber further underscores his commitment to understanding the toxicological effects of welding emissions, making him a key figure in advancing welder health protection.
